The MIC2920A-12WS from Microchip Technology is a fixed 12V low-dropout linear regulator capable of delivering 400mA. With a dropout voltage of 0.75V at full load, it efficiently regulates from 24V industrial rails or 13.8V automotive supplies. The SOT-223-3 package offers reliable thermal performance. Its 300µA quiescent current makes it suitable for always-on applications. This regulator is a robust choice for industrial, automotive, and telecom systems requiring a stable 12V output.
- Wide Input Compatibility: Handles up to 26V, ideal for 24V industrial and automotive systems.
- Low Dropout: 0.75V at 400mA maximizes efficiency with minimal headroom.
- Reliable Package: SOT-223-3 provides good heat dissipation for continuous loads.
- Moderate Quiescent Current: 300µA balances performance and standby power.
